About the Airtac SAID80 Double Rod Cylinder SAID80BX450S
The AirTAC SAID80X450-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 450mm stroke and an 80mm bore. Because the twin SUS304 stainless steel rods occupy both sides of the piston, the annulus area is identical in both directions, yielding exactly 2268N of force at 0.5 MPa on extend and retract. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet pairs directly with CMSE reed and DMSE electronic solid-state switches for dual-side position detection.
A defining consequence of the through-rod design is that a single piston drives a rod out of both end covers, allowing you to mount the primary workpiece on one end and a cam, secondary tool, or limit flag on the opposite end. This configuration provides superior anti-rotation guidance compared to a single-rod SAI cylinder. The unit uses adjustable air cushions at both ends to decelerate the piston near stroke limits, but note that this cushioning is not a locking mechanism; the cylinder will drift if air pressure is lost.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX450S Is Used
Symmetric Force Transfer
Drives a heavy 450mm stroke transfer carriage with equal push and pull force, ensuring consistent cycle times regardless of travel direction.
Dual-Side Actuation
Mounts a primary forming tool on the front rod and a secondary cam on the rear rod to trigger a separate pneumatic valve at the stroke endpoint.
Anti-Rotation Slides
Leverages the dual SUS304 stainless steel rods to guide a heavy vertical slide, preventing unwanted torsion and maintaining precise load tracking.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX450S the Right Cylinder?
Select this 80mm bore model when an application demands symmetric force and speed both ways, offering 2268N at 0.5 MPa or 3175N at 0.7 MPa in each direction. If your payload requires less force, stepping down to the 63mm bore yields 1402N at 0.5 MPa, while moving up to the 100mm bore provides 3681N at 0.5 MPa. The SAID80X450-S is dimensionally interchangeable per ISO 15552, uses a PT G3/8 port, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts (omitting FB, CA, CB, and CR).
With a 450mm stroke, the unsupported rod length increases the risk of side-load bending and bearing wear. For this longer stroke, implementing an external guide rail is strongly recommended to prevent excessive radial stress on the rod seals. Furthermore, if the machinery must hold a load statically without live air pressure, a plain SAID will not suffice; consider an AirTAC SAIL lock cylinder, a BSAID clamp-lock, or an external pilot-operated check valve.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID80 Double Rod Cylinder SAID80BX450S FAQ
The double-rod design subtracts the rod area from both sides of the piston, resulting in equal force for both extend and retract. It provides 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa in each direction.
Yes, the SAID80X450-S is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 profile cylinders. It features PT G3/8 ports, a -S magnet for CMSE/DMSE sensors, and SUS304 stainless steel rods.
